Abstract

The invention discloses a data line and charging equipment, and belongs to the technical field of communication. The data line comprises a first Type-A interface, a Type-C interface, a single bus controller and a switch module, wherein each of the first Type-A interface and the Type-C interface comprises a CC pin, and the CC pins in the first Type-A interface and the Type-C interface are communicated through CC wiring; the switch module is respectively connected with the CC wiring and the single-bus controller; and when the single-bus controller determines that the data line is connected witha matched first charger based on the identification information transmitted on the CC pin, the switch module is communicated with the CC wiring under the control of the single-bus controller. According to the embodiment of the invention, when the data line with the Type-A interface is connected with the matched charger, the CC wiring is communicated, so that the PD charging function is supported.

Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to a data line and a charging device. Background technique [0002] With the development of science and technology, the application of fast charging is more and more extensive. [0003] In related technologies, the power delivery (Power Delivery, PD) protocol is usually used for fast charging, and a charger supporting PD protocol charging needs to use a CC signal line for communication. The charger supporting PD protocol charging usually adopts the third standard ( Type-C) interface, and with a Type-C to Type-C data cable. For a charger using the first standard (Type-A or Standard-A) interface, it communicates through the D+ / D- signal line and cannot support PD protocol charging, so that the data line with the Type-A interface does not support PD Charge. Contents of the invention [0004] The purpose of the embodiments of the present application is to provid...
